Multi-line ellipsis made possible

FTEllipsis

Solves the problem of applying ellipsis (…) on a multi-line block of text at the point it overflows its container. Ellipsis will work in conjuction with CSS column-count if you wish.

Results are best in webkit browsers due to the availability of webkit-line-clamp. For non-webkit browsers FTEllipsis falls back to clamping text and positioning an element over the end of the overflowing line, allowing the developer to style this however they wish.

Getting Started

NPM

$ npm install ftellipsis

Bower

$ bower install ftellipsis

or download the production version or the development version.

Examples

• Primary
• Single Line

Usage

var element = document.getElementById('my-element');
var ellipsis = new Ellipsis(element);

ellipsis.calc();
ellipsis.set();

Requirements:

• The element must have a fixed height so that content overflows.
• The element must have child elements (eg. <p>s).

Unsetting

Unsetting an ellipsis instance removes any styling.

ellipsis.unset();

Destroying

Destroying an ellipsis instance resets the instance back to it's original state, unsetting internal variables and state.

ellipsis.destroy();

Tests

$ npm install
$ npm test

API

Options:

• container A parent container element
• reRender Forces a redraw after ellipsis applied
